Photosynthesis Lab:
-Introduction:
In this experiment, my group (Max Vonblankenberg, Rick York, Cris Boggio, & Garrett Hoefer) and I must test how certain colors affect the growth, photosynthesis process, and production of energy. I need to plant this in my mind before it truly leaves. Yes. Plant puns are cool, but there isn't enough of them :(
~Purpose:
1.) How does different colors of light affect the growth of plants?
2.) How much starch is created at the end of each result?
~Hypothesis:
My group (Max Vonblankenberg, Rick York, Cris Boggio, & Garrett Hoefer) came up with a hypothesis that the higher the intensity, the faster photosynthesis occurs, but with a lower wavelength, the more energy is created, such as glucose and starch.
~Materials:
- Scissors
- Tape
- Black construction paper
- Blue, Green, & Red Cellophane
- Potted Plant with a lot of Leaves
- 5 Test Tubes
- Sharpie (marking test tubes)
- Forceps
- 400mL Beaker
- 5 petri Dishes
- Iodine Solution
- Paper Towels
~Procedure:
On the first day, my group and I covered leaves with the colored cellophane and black paper; 3 leaves each. We also had leaves that didn't have anything on it to test a regularly growing leaf and compare it to the affected ones.
The next day, we took off the cellophane and black paper from the leaves, pulled off the leaves off it's stem, and then removed chlorophyll by placing it in hot ethanol. After that, we tested for starch using iodine on each piece of leaves.
~Results/Conclusion:
-Uncovered Leaves: Tested Positive for Starch
-Leaves with Cellophane: Still tested Positive for Starch, but much weaker
-Black Paper with Leaf: Didn't help the leave grow. Tested Negative for Starch
This experiment proves that the amount of light isn't the only thing that affects the photosynthesis of leaves and plants, but so does the wavelength. The light that was being give to the plants with cellophane was the same was regular, uncovered leaves (at the same distance from the light source).
~Reflection:
This experiment was very interesting. I never realized that the amount of distance could also affect the photosynthesis of plants, not just the amount. Although technically the farther the light the less of the amount, I didn't think the cellophane would affect anything. The hardest part about this project though was the collaboration. Having 5 people in one group isn't a good idea, especially if you are all good friends and all don't have things to do except start a conversation about Skeletor and/or Space Jam remixes (which are AWESOME by the way). Anyway, the point of me saying this is that smaller groups are better and teach you how to work with others. This also goes into what I want to do for next time; be in a new group of people and it be smaller. As much as I love hanging out with my friends, I want to be able to help my group and get things done more efficiently. Hope I can do better next time.

The following link is to a remix I know and love and isn't apart of this Photosynthesis Lab. If you think you can handle the Jam and Slam at the same time, you can watch this link, but be warned, no man nor women has come out as the same person as they once before after watching this video. Viewer Discretion is Advised.
~BONUS: ( I am sorry I couldn't resist)
